Hi, at our Science in the Van lesson I learnt three things.
Firstly, I learnt the three states of matter, it's Solid, Liquid and Gas. Secondly, I learnt that Vinegar can create gas by doing an experiment using a balloon. Thirdly, I learnt that if you put sodium polyacrylate in a cup and leave it for a while and then it will turn into a solid.
The most fun part was when I was demonstrating the three stats of mater. The most interesting thing I learnt is sodium polyacrylate can turn into a solid. Have you ever watch science in the van? You really should.
